introduction
Oral cancer is primarily a disease seen in elderly men (50–80
years of age) with a decades-long history of smoking, and consumption of over 20 cigarettes and 100 g of alcohol a day.1 Its presentation
in younger patients (<35 years) is fortunately rare, with an incidence
between 0.4% and 5.5%.1 However, when cases do present, they are
often misdiagnosed, leading to inappropriate delays in treatment,
and worsening prognoses.2 This bears significant implications for
young patients, with the potential for long-term functionally debilitating sequelae. With this in mind, we report a case of oral tongue
squamous cell cancer (OTSCC) in a young Caucasian female, with a
focus on her diagnoses and subsequent post-surgical quality of life.
case report
A 25-year old Caucasian female presented to a dentistry clinic,
complaining of a left-sided lesion on her tongue of 13 months duration, which had markedly increased in size within the past month.
She reported an impact on her speech and eating patterns, and expressed worry about a malignant etiology. The patient had initially
believed the lesion to be a chancre sore, but decided to seek help as
the lesion had continued to grow.
The patient had an intermittent smoking history of an unspecified duration, during which she smoked up to 5–10 cigarettes daily.
She also had a five-year history of drinking, a period through which
she consumed 8 drinks per day, for four days a week. She denied
experiencing night sweats or fevers, although she reported losing
weight from a markedly reduced food intake. Her paternal grandfather had died from metastatic esophageal cancer, and her maternal
grandfather was diagnosed with colon cancer.
The dental practitioner reassured her (allaying her fears of
cancer), filed down her teeth, and scheduled a follow-up appointment in 2 weeks’ time, during which her presentation changed
significantly. She started experiencing constant headaches, and
the lesion grew purulent, significantly affecting her ability to eat.
Finding that conservative management with salt and water, as well
as peroxide was futile, she visited her university walk-in clinic to
receive antibiotics, noting once again that the physician failed to
discuss the possibility of a malignant etiology. Re-visiting her dental practitioner at her follow-up appointment, the rapid change in
presentation quickly prompted a referral to a dental specialist at an
academic care centre. Although the appointment wasn’t for another
four months, the exponential growth of the tumor led the patient
to successfully reschedule the appointment to a closer date, within
two months’ time. A physical examination prompted the specialist to quickly refer the patient to an otolaryngologist, who saw her
within the week.

The surgeon prescribed her Tylenol-Codeine #3, which she
took with Ibuprofen and Acetaminophen for pain management. Her
diet was reduced to soft meals, consisting of pudding, apple sauce
and yogurt. Three weeks later, after confirmation through biopsy of
a T2N0 squamous cell carcinoma of the oral tongue, the patient underwent a selective neck dissection. A left-sided hemiglossectomy
removed the carcinoma, and a fasciocutaneous radial forearm free
flap from the right arm replaced the defect. The skin defect was
replaced using a graft from the right hip. A tracheostomy was performed, and a feeding tube was inserted. The absence of metastasis
precluded the need for chemotherapy or radiation treatments. The
patient remained hospitalized for an additional two weeks.
Post-surgical QoL issues circled around dysfunction of the left
shoulder muscles, sensitivity of the left sided face and right arm,
and with problems inherent in having a tracheostomy and feeding tube. The patient’s face was numb for an unspecified duration
post-surgery, and her tongue was significantly swollen for a week.
In addition to the cast on her right arm, and IV’s in her left, communication (both verbal and written) during that week was significantly impaired.
The patient received integrated care from a team of inter-professional allied healthcare workers. A respiratory therapist aided
her in coughing exercises to prevent aspiration pneumonia from her
tracheostomy; a physiotherapist aided her transition off the tracheostomy, familiarizing her with breathing exercises, and encouraging
the change from bed-rest to ambulation; a speech language pathologist performed pre- and post-op assessments to evaluate standard
articulation and swallowing; a nutritionist made recommendations
post-surgery to assist the patient’s food intake; and a home care
nurse assisted the patient in showering and re-dressing the cast on
her right arm. The patient had pureed meals for 2 months, and continued her pain medications for one month post-surgery. With the
assistance of her parents and her healthcare team, the patient was
able to recover and return to school for the next academic year. Following surgery, the patient has had annual follow-up appointments
with no evidence of recurrent disease to date. She subsequently quit
smoking, and has since given birth to her first child.
The patient still suffers from ongoing QoL issues. The patient has a persistent dry mouth, and has reduced sensation of
her left-sided tongue, occasionally not noticing when she bites on
it. She is unable to differentiate between soft and hard bites, and
has changed her eating patterns, shunting food from the right side
of her mouth to make use of her remaining taste buds. This has
spawned dentition problems, including right-sided gum loss and
left-sided gum growth. She has recurrent neck and jaw pain, which
she treats with Tylenol. She has also noticed changes in her facial
features, with her left-sided face appearing ‘droopier’.

case report
discussion
epidemiology
Oral tongue squamous cell carcinoma (OTSCC) is the most
common tumor in the oral cavity.2 Although the overall incidence
of OTSCC has remained stable from 1975 to 2007, its incidence has
been increasing in women, specifically in young, Caucasian females
aged 18–44 years.1 Unfortunately, as is evident in the case presentation, there is a stigmatized approach to younger female patients
with suspicious oral lesions. Raising awareness on these rising incidence levels will alert healthcare practitioners to atypical presentations, and reduce any delays these patients may experience in
receiving appropriate care.
risk factors for younger patients
Although the literature is uncertain and the topic still highly
debated, it has been claimed that younger patients have more aggressive disease, with a higher incidence of local recurrence or regional lymph node involvement after treatment, and higher mortality rates.1 Young patients often present with little-to-no risk
factors (alcohol, tobacco and betel nut exposure), or with a history
of tobacco and alcohol intake significantly shorter in comparison
to their older counterparts. Given this disparity, researchers have
proposed other risk factors to account for the etiology of these oral
cancers, such as immune deficiency states, genetic factors, dietary
factors, and viral infections (such as herpes simplex virus and human papilloma virus).1 The association between oropharyngeal
cancer and HPV infection is controversial at best, and significant
research has been focused on screening for specific virally-associated mutations of known tumor suppressors, oncogenes, and replication pathways.2 Unfortunately, no clear inciting pathway has been
identified to this date.
conclusions
Although there is adequate research into QoL for oral cancer
patients, most of the current literature solely investigates elderly
patients with significant histories for known risk factors. There is
a noticeable lack of research into QoL specific to younger oropharyngeal cancer survivors, namely OTSCC survivors. The rising incidence of these cancers in the younger population raises the need for
further studies to be done, in order to ensure that younger patients
return to a fruitful life with limited functional disabilities.

quality of life
Research into QoL issues for young oral cancer patients is a
rather new and emerging concept. Thomas et al. performed a retrospective case series and questionnaire survey for patients treated
for oral cancers during a 25-year period, when they were 40 years
of age or less. They found that age at diagnosis and duration of follow-up did not correlate with overall QoL or health-related QoL.
Approximately 77% of patients rated their overall QoL as outstanding, very good or good, with the key problematic domains lying
within appearance, mood, salivation and shoulder function. Only
radiotherapy adversely affected the overall QoL.3 In addition, a systematic review by Carranza et al., found that younger oral cancer
patients show more emotional and role dysfunctions than older
patients, and are at higher risk for psychological stress and an increase in symptoms–such as dry mouth–in the first post-treatment
year. Marital status seems to be a protective prognostic factor for
survival and recurrence in comparison to those who live alone, possibly due to better hygienic habits, and fewer delays in diagnosis
and treatment.4
